Get ready for real conversations.
Without saying a word.
Reverb is spaced-repetition Spanish and French for serious learners who are done with apps built like children’s games. Practice silently — on the train, at your desk, in a waiting room. No cartoon mascots, no confetti, no talking to your phone in public.

You didn’t put in months to freeze the moment someone actually speaks to you.
The most popular apps are designed to keep you playing — streaks, badges, a mascot nagging you back. That’s a game, and you might be winning it. It still isn’t teaching you to hold a conversation. Reverb is built around one question: when it’s your turn to speak, will the words be there?
Learn the words your life actually uses.
A children’s app teaches you “the bear drinks milk.” Reverb steers your lessons toward your job, your trip, your hobbies — so you’re practicing the conversations you’ll actually have, not vocabulary you’ll never say.

Stuck? Get a real answer.
Tap the word that tripped you up and get a clear explanation of exactly what you missed, in context — not “wrong, try again.” No re-guessing until the timer runs out.
Learn where you actually are.
Other apps make you talk at your phone — useless on a subway, at your desk, in a quiet office. Reverb is built to be practiced in complete silence: you can learn in the back of a meeting and no one would know. See for yourself in the demo.

Every minute moves you forward.
No animations to sit through. No celebration screens. No mascot. Just the next rep, and the next — far more real practice per session than any app that has to stop and throw confetti.

Skip what you already know.
A two-minute placement test drops you in at the right level — instead of restarting from “hello” for the fourth time.
Sentences, not flashcards.
You learn vocabulary and grammar inside real sentences — the way recall actually sticks — and one sentence sharpens several things at once.
Two different things, sold as the same thing.
| Gamified apps | Reverb | |
|---|---|---|
| Built for | Habit-streaks and badges | Serious learners who want results |
| Practice | Talk out loud or tap bubbles | Silent recall, anywhere |
| What you learn | A fixed cartoon curriculum | Words from your life |
| When you’re stuck | “Wrong, try again” | A real explanation of what you missed |
| Costs you | Months, with little to show | A focused 15 minutes a day |
Built on the science of not wasting your time.
Spaced, not crammed.
Reviews land right before you’d forget — the single most-replicated result in memory research, confirmed across hundreds of studies.1 Cramming feels productive. It isn’t.
Recalled, not recognized.
You produce the answer yourself, even when you guess wrong — active recall that’s been shown to roughly double retention over just rereading or tapping the right bubble.2
Personalized, not scheduled.
Reverb’s algorithm tracks what you specifically forget and when, so you’re never reviewing what you already know — cutting wasted review time by roughly a third compared to older fixed-interval systems.3
None of this is new. It’s just usually buried under streaks and mascots instead of doing the work. Your time is the input here — every design decision exists to get more fluency out of the minutes you actually give it.
